When was the last time you saw a kite-like device flying on a boat? While it may appear to be a fun toy at first, a special device called SkySails is helping these boats save money on fuel by harnessing the power of air, reports AFP.
The 160-square-metre (524-square-foot) kite, tethered to a yellow rope, can sail 500 metres into the skies where winds are both stronger and more stable, according to the 38-year-old Wrage.
